ALBERT E. HOLADAY, OF NAUGATUCK, CONNECTICUT, ASSIGN OR TO AMERICAN WRINGER COMPANY, OF WOONSOCKET, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed August 29, 1917. Serial No. 188,756.

To all whom it may concern Be it known that I, ALBERT E. HOLADAY, a citizen of the United States, residing at N augatuck, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Pressure- Roll Releases for Clothes-Wringers, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to a pressure roll release for clothes wringers, and is an improvement on my Patent #1,220,127, granted to me March 20, 1917, the object being to provide means for returning and holding the locking member employed for holding the section of the breakable bar in locked position.

. Another object of my invention is to provide a breakable bar having a spring-actuated locking member which is exceedingly simple and cheap in construction, the spring being arranged in an opening formed in one of'the abutting ends of the sections of the bar and engaging the locking member in such a manner as to return and hold the locking member in position to retain the sections of the breakable bar in alinement with one another in order to allow the proper pressure to be exerted on the pressure roll.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings,

Figure 1 is a side elevation of an ordinary clothes wringer showing the application of my improved construction of pressure release thereto, the breakable bar being shown raised in dotted lines;

Fig. 2 is an enlarged longitudinal section through the breakable bar showing my improved construction of spring for the locking member; and

Fig. 3 is a perspective view of the locking member and of the end of one of the sections of the breakable bar showing the spring for restoring and holding the locking member in locked position.

Like numerals of reference refer to like parts in the several figures of the drawing.

In the drawing I have shown a clothes wringer of the ordinary construction composed of a frame 1 having slotted side bars 2 in which are mounted suitable bearings carrying pressure rolls 3 and 4, the upper bearing being provided with the usual spring supports 5 on which are mounted pressure springs 6 engaged by hearing plates '7 carried by the ends of a pressure bar 8.

Arranged over the upper ends of the side bars 2 are caps 9 preferably formed of castings having overhanging lips 10 extending over the slots of the side bars as clearly shown in Fig. 1.

Arranged under the'overhanging lips 10 of the caps 9 are the ends of a sectional top bar 11 formed of two sections pivotally connected together by a hinge 12 arranged on the under side of the sections as clearly shown in Figs. 1 and 2 in order to allow the sections to move upwardly as shown in dotted lines in Fig. l. The free ends of the sectional top bar are rounded on the under side as shown in Fig. 2, and are provided with boxes 13 carrying pressure screws 14: adapted to engage the bearing plate 7 of the pressure bar 8 so as to adjust the pressure on the pressure rolls in the usual manner.

Pivotally mounted on the end of one of the sections of the top bar 11 is a locking member 15 arranged. between the abutting ends of the sections of the top bar in such a manner that the same is free to swing transversely on its pivot 16. Thelocking member 15 is provided with locking hooks 17 and 18 extending in opposite directions adapted to engage the upwardly projecting angled ends 19 of plates 20 secured on the top of the sections of the top bar, said angled ends being mounted as shown at 21 in order to allow the hooks 17 and 18 to readily pass over the angled ends and off of the same.

The locking member 15 is provided with a plate 22 at each end as clearly shown, and the construction thus far described is substantially the same as shown in my patent granted March 20, 1917.

One of the abutting ends of the section top bar- 11 is provided with a bore 23 in which is arranged a spring 24:, the inner end of which is driven into the bottom of the bore as clearly shown in Fig. 2, the outer end projecting outwardl beyond the end of the section of the top ar and is adapted to extend into an aperture 25 formed in the locking member 15. The spring is preferably formed of a bar of spring metal which permits the same to be readily inserted within the section of the top bar, and in the position as shown in Fig. 2 the locking member is held in locked position thereby. moved transversely of the sections in order to release the same so as to allow the sections to move into position as shown in dotted lines in Fig. 1, the spring is placed under tension and as soon as the push plate is released the locking member is returned to locked position.

It will be seen that by this construction when it is desired to place the sectional bar to normal position within the wringer frame it is only necessary to release the pressure on the pressure screws and force the pressure bar downwardly, and by pressing on one of the push plates 22 the hooks will be thrown out of the path of the angle members so that when released the locklng member will engage the hooked ends and hold the sections of the breakable bar in alinement in order to allow the desired pressure to be placed on the pressure rolls of the wringer.

From the foregoing description it will be seen that ll=have provided a spring-return locking member for the sections of the breakable bar which is exceedingly simple and chea in construction, the spring being conceale within the end of one of the sections of the bar.

I claim:

1. breakable bar for clothes wringers, comprlsing a pair of sections pivotally connected together, a locking member mounted on the abutting end of one of said sections for Lockin said members together, said When the locking member is aeaooe locking member having an aperture and a bar spring mounted in the end of one of said members extending lnto the aperture of said locking member for normally holding said locking member in looking position.

2. A breakable comprising a pair nected together, a

bar for clothes wringers, of sections pivotally conlocking member mounted on the abuttingend of one of said sections having oppositely disposed hooks, plates carried by thev abutting ends of sald sections having upwardly projecting adapted to' be engaged by said hooks, and a spring arranged within the end of one of said sections engaging said locking member for holding said locking member in locked position.

3. A. sectional breakable bar for clothes wringers, composed of a pair of sections pivotally connected together, each section having a plate provided, with an upwardly projecting portion secured thereto, a transverse movable locking member mounted on the end of one of said sections having hooks for engaging the upwardly projecting portions of said plates, said locking member having an aperture, one of the sections of said bar being provided with a bore in alinement with said aperture, and a bar spring arranged within the bore extending into the aperture of said locking member for returning and locked position.

In testimon whereof I hereunto affix my signature in t e presence of two witnesses.
